Kernel-4.18.0-80.el8_atmel-isc

Atmel Image Sensor Controller (ISC)

Required properties for ISC:

• compatible
  Must be “atmel,sama5d2-isc”.
• reg
  Physical base address and length of the registers set for the device.
• interrupts
  Should contain IRQ line for the ISC.
• clocks
  List of clock specifiers, corresponding to entries in
  the clock-names property;
  Please refer to clock-bindings.txt.
• clock-names
  Required elements: “hclock”, “iscck”, “gck”.
• #clock-cells
  Should be 0.
• clock-output-names
  Should be “isc-mck”.
• pinctrl-names, pinctrl-0
  Please refer to pinctrl-bindings.txt.

ISC supports a single port node with parallel bus. It should contain one
‘port’ child node with child ‘endpoint’ node. Please refer to the bindings
defined in Documentation/devicetree/bindings/media/video-interfaces.txt.

Example:
isc: isc@f0008000 {
compatible = “atmel,sama5d2-isc”;
reg = <0xf0008000 0x4000>;
interrupts = <46 IRQ_TYPE_LEVEL_HIGH 5>;
clocks = <&isc_clk>, <&iscck>, <&isc_gclk>;
clock-names = “hclock”, “iscck”, “gck”;
#clock-cells = <0>;
clock-output-names = “isc-mck”;
pinctrl-names = “default”;
pinctrl-0 = <&pinctrl_isc_base &pinctrl_isc_data_8bit &pinctrl_isc_data_9_10 &pinctrl_isc_data_11_12>;

port {
    isc_0: endpoint {
        remote-endpoint = <&ov7740_0>;
        hsync-active = <1>;
        vsync-active = <0>;
        pclk-sample = <1>;
    };
};

};
